COM in Borland?

[XxReaperxX]

I have a COM object that was written in VC++. I've got all the interface inforamtion and Interface ID's for it.

I have a Borland MFC C++ program as well.

My goal is to get this COM object to work with my Borland C++ program, is this possible? Can you interface a COM object with Borland?

you should use CoCreateInstance with CLSID of object you're looking for. You get an interface pointer and work with it or query other interfaces. Pay attention on return codes.

CoInitialize(NULL);
IDispatch* pDisp;
IUnknown* pUnk;
CLSID clsid;
CLSIDFromProgID(cApp,&clsid);
CoCreateInstance(clsid,NULL,CLSCTX_SERVER,IID_IUnknown,(void FAR*FAR*)&pUnk);
pUnk->QueryInterface(IID_IDispatch,(void**)&pDisp);
..work here
pDisp->Release();
pUnk->Release();
CoUninitialize(); John Fill
